PLOT: Reunited

Two siblings who were adopted separately at an early age have been searching for each other for years. When they are finally reconnected, they come to find out that they have been living on the same street for almost 2 years! You can have them never have met each other, or you can go a step further and they could have had many a run in with each other and either become best friends or possibly even dislike one another for whatever reasons.
